Just noticed you have a turbo. That probably means you have a fairly bad induction leak in the path between turbo and cylinder head. When you unplug the MAF, the car goes to a default set of injector firings based on rpm and will run decently, with bad mileage and high emissions. When you plug in go...

The late P80 cars have thermostatted PCV. Yeah! I'm convinced they clog much less than early P80s. I changed my oil with Dino every 5k with this car and really had minimal sludging. Reinstalling the manifold is hard though as you have extra stuff. 1 turbo induction manifold to ETM 2 electrical ETM, ...

A leak that slow won't carry oil out in significant qty. if you serviced the system, I would replace the receiver/dryer and add the Volvo recommended amount of PAG for that component only. NOTE! There are no high/low pressure connections on the compressor. Thus is it only possible to check the opera...

The paper won't make it into the oil, it will get shredded by the turbo, sucked into the combustion chamber and get burned up either in the cylinders or in the cat. IF it makes it through the intercooler. I think the internal on the intercooler is fine enough it will effectively catch big pieces. If...

Motorola didn't design this chip for Volvo, it was designed for multiple applications outside automotive. You are reading way too much into this, the design of parts like these is driven by supply chain considerations much more than EE. Over-riding a fuel pump relay long term with either mechanical ...

I think you are in the ward next to mine - do you have a leave pass this weekend ??

What specifications does the oil claim to meet? Check your owners manual to see what's required got your car, as a first step. Deciding if you believe the spec would. Be step two, to frugality nirvana. Draining the oil out of car one and putting it into car 2 would be step three. There are 9 more st...

Do the simple things first, replace the reservoir. Unless you overheated it, no reason to think loss of pressure from crack isn't the root cause at this moment.

Welcome to the P2 forum and world!

The Denso ( I think) management system in the P2 does this to help heat the O2 sensor.

I use those 20 seconds to roll my ...eyes.

It's normal operation.
